Recently, micro-surfacing is more widely used to protect the asphalt pavement for its superiority in China. This paper investigated the effects of the waste rubber on the micro-surfing material. First, the noise reduction mechanism was analysis. Then, the surface performance of the micro-surfacing mixture was characterized in the laboratory. Sound absorption and vibration damping theory was put forward in this paper. The addition of crumb can slightly improve the surface performance of the pavement.
